For the rich characteristics of China's stainless steel scrap resources, private enterprises have long known. Foshan, Guangdong, Qingyuan, Zhejiang, Taizhou, Zhejiang and other places have emerged a number of workshops that select scrap from waste equipment (commonly known as foreign garbage).
Some private enterprises have also begun to use the powder in the process of stainless steel production and product manufacturing, and environmentally-friendly additional products (water, sediment, etc.) to process and refine, and use it as a charge in steel production. However, the overall situation is still under development, and there is also a lack of research data, which is not included in the above forecast. It is conservatively estimated that the nickel content of domestic stainless steel scrap is also above 80,000 tons in 2005; in 2010, it reached more than 150,000 tons; in 2005, the domestic chromium scrap contained more than 270,000 tons; in 2010, it reached more than 480,000 tons. Therefore, attaching importance to the recovery of stainless steel scrap is very important for the healthy development of the domestic stainless steel industry.
Technical experts should strengthen the research on the refining of powders and environmentally friendly additional products (water, sediment, etc.) in the production of stainless steel and products. Roughly calculated, the amount of stainless steel scrap steel contained in the "three wastes" produced from the production of crude steel to cold-rolled sheet is about 5% of the crude steel volume. Adding the two together, in 2010, this part of stainless steel scrap resources is about 80. Wan T.
